Piston Seal PSP Profile

Piston Seal PSP Profile


Parker’s PSP seal is a squeeze type, bi-directional piston seal for use in light to medium duty hydraulic applications. Available from proprietary Parker polyurethanes, the PSP offers low friction, abrasion and extrusion resistance. The nitrile elastomer energizer ensures resistance to compression set to increase seal life. The PSP seal’s geometry provides a fluid reservoir between the two sealing lips which holds system fluid, resulting in reduced breakaway and running friction. Designed to retrofit grooves for a single O-ring or an O-ring with two back-ups, the PSP profile is easy to install and resist rolling and twisting in long stroke applications.

The PSP profile is sold only as an assembly (seal and energizer). See part number nomenclature.
